Preface

Apache Storm is a powerful framework for creating complex workflows that ingest and process huge amounts of data. With its generic concepts of spouts and bolts, along with simple deployment and monitoring tools, it allows developers to focus on the specifics of their workflow without reinventing the wheel.

However, Storm is written in Java. While it supports other programming languages besides Java, the tools are incomplete and there is little documentation and few examples.

One of the authors of this book created Petrel, the first framework that supports the creation of Storm topologies in 100 percent Python. He has firsthand experience with the struggles of building a Python Storm topology on the Java tool set. This book closes this gap, providing a resource to help Python developers of all experience levels in building their own applications using Storm.
